least, is the backing or holding mechanism,
which backs one end of each growing stack and is moved along to give space for further coins to be added. For example, when these machines are speeded up beyond certain limits, coins sometimes creep out of a growing stack, and in machines where the coins are stacked horizontally at least, the first coin or first few coins of a new stack sometimes fall over instead of remaining upright. I
have found the fault to lie with the backing mechanism.
According to my invention therefore, I build the backing mechanism in a number of parts as it were, using one backer to back the first coins of each new stack and then another backer to take up the backing function and carry it farther from the point where the first leaves off, and I take the thrust of the backing mechanism 01f the stack, at least after enough coins have been assembled in the stack to' render creepage likely, and while arranging the backer to hold the coins inplace, positively hold the backing mechanism at all times far enough from the opposite end of the growing stack to permit the coins to rest easily in their places. 7
In the accompanying drawings, Fig. 1 is an elevation of a coin stacking mechanism emso bodying my invention. Fig. 2 is a side view of the major portion of the mechanism of Fig. 1, a partly completed stack being shown in position and parts being broken awa'yifor illustrative purposes.
Fig. 1, showing the placement of the coins on the stacker bars.
In the coin stacking mechanism illustrated, the coins are fed edgewise, one by one,
5t) along a track or path, the bottom of which Fig.3 is a vertical. section, at right angles to the drawings 111 is indicated at 1. At the 'end of this path or track, they pass underneath a guide or latch 2 which is pressed resiliently against the edge of each coin. Thence the coins are thrust face-wise onto and stacked, successive- 1y, on two horizontal stacker bars 3 and 4: by the reciprocating stacker pins 5 as the coins come to the position occupied by the coin 6 inrFig. 8; these stacker pins are reciprocated by an appropriate swinging arm 7 for which the spring 8 on bolt 9 is a resilient back-stop. The stacker bars 3 and 4: are placed a little lower level than the track 1, so that as the stacker pins 5 push a coin onto the stacker bars and 4, the lower edge of this coin passes below the bottom of. the track 1; likewise the top of the coin passes in front of a lip on the latch or guide 2 as illustrated in Fig. 1. The latch or guide lipand the face of the plate 14: forming the bottom of the track- 1 thus constitute abutments against which the coin is pressed or leans until the nextcoin reaches the positionof 6 in Fig. 3 and then thrusts it along the stacker bars and takes'its place.
coinsof different diameters, the plate 14 is adjustable vertically and the stacker bars 3 and dare mounted for adjustment both vertically and horizontally. The plate 14 is mounted and guided on the frame member 15 111 a suitable manner. The stacker bar 3 is .mounted in an arm 16 fastened to a sleeve 17 Wl11Cll is free to turn on the pin 18, and likewise the stacker bar d is carried by an arm 19 carried by asleevc free to turn on the fixed -.pin 20 which is parallel to the pin 18. Both these pins are mounted in 15. A pin 21' mounted in sliding plate 14: extends into oppositely inclined slots 22 pierced in the arms 16 and 19, each slot being parallel with its arm. Hence it follows that moving the slide .14 downwardly to depress the bottom 1 of the coin track in order to permit the passage 7 of a larger coin along the track, turns the arms 16 and 19 in opposite directions to a corresponding degree, thus separating the stacker bars 3 and 4 and dropping them down to a little distance corresponding to the depression of the bottom 1 of the track.
'75 In order that the machine may handle 1V ith such stacking mechanisms it has been customary to use a spring-pressed float as a backing or holding mechanism to hold the coins upright on the stacker bars 3 and 4 be tween the float and the abutments on 2 and 14, this float being substantially like the float 30 mounted to slide on the stacker bar 3 and provided with a spring 31 to hold it in position and return it toward the abutments as soon as a finished stack is removed from the stacker-bars. As an incident, the float 30, under the pressure of the spring, thrusts the stack against the abutments between movements of the stacker pins 5 adding new coins to the growing stack. According to myinvention, however, while I permit the float 30 to come sufficiently close to the end of the stack to keep the coins upright on the stacker bars 3 and 4, I relieve the stack of this thrust of the spring float. To this end I provide a rack bar 32, extended substantially parallel to the stacker bar 3, and for co-operation therewith a pawl 33 hinged at 34 in guideways formed on thefloat 30. By means of a spring 35 extending between an eye 36 on the body of the float and :a pin 37 on one end of the pawl, the oppositeend of the pawl 33 is normally kept in engagement with the teeth of the rack'bar 32. Preferably these teeth are so numerous that each unit of length of rack bar equal to the thickness of one coin,
contains two or more teeth. As the stacker pins 5 are thrust out to push another coin onto the stacker bars 3 and 4, they push the whole growing stack, and therewith the float 30, to the left in Fig. 2, and in order to take care of coins of different thicknesses and to assure that each coin passes well off the bottom of the coin track, the stacker pins 5 thrust the stack well to the left. As the stacker pins 5 retreat again to the right howfments on 2 and 14. The float now retains the coins in a substantially upright position as before between the float and the abutments on 2 and l4,'but between these two end sup- 1 ports the coins now rest lightly.
lever 38, tends to normally hold the lever in j The rack bar 32 is carried on a lever 38, the sleeve 39 of which is mounted on pin 18; a shoulder 40 on sleeve 17' limits the upward movement of the end of the lever carrying the rack bar 32 to a position in'which the rackbar is suitably engaged by the pawl33. A spring 41 mounted between a pin 42 on a projection from sleeve 1;? and pin 43 on the its upward or pawl-engaging position against the shoulder '40. By thus controlling 3, it is evident that the rack bar 32 follows themovement of the float as the stacker bar 3, which carries the float, is moved to a new position to take a different size coin. When a completed stack is lifted off the stacker bars 3 and 4 and a new stack is to be begun, lever 38 is rocked to depress the rack bar 32 to release the pawl 33 and spring 31 then re-' turns the float 30 toward the coin track 1. In order that the beginning of the new stack need not await the arrival of the float 30,1 have provided another coin stacker or holding mechanism for the first few coins of each stack. This is in the form of a plate 48 sliding at 49 on the face of plate 14 (being held thereon .by gib'bs or guides), this plate'48 sliding between the stacker bars 3 and 4 and transversely of the latter. The finger or coin-engaging portion of 48 is displaced sufliciently from the face of the sliding plate 14 to receive a few coins, say three, as illustrated in Fig. 3. As a stack is finished and taken from the stackerbars 3 and 4, this temporary or supplemental backer 48 is pushed upwardly to the position shown in Fig. 3 where it is, in position to support the first coin or coins pushed off the coin track 1 by the stacker pins 5. When the float 30 has reached the backer 48, the latter is retracted again, i. e.,. slipped downwardly to its position in Figs. 1 and 2, the float 30 takes over its function, and the stacking operation then continues as before described. g
The pawl and rack bar are released, one from the other, to permit the return of the float 3O to its starting position substantially simultaneously with the upward movement of the. supplemental or temporary backer 48 to its backing position, and this'occurs,
usually, about simultaneously withthe removal of afinished stack from the stacker bars 3 and 4. Such operation is herein illustrated. The cam 52 on shaft 53 controls and times both the backers. The shaft 53 can be rotated in any way'to bring about the starting of a new stack at the proper time, the actuation of the backers being brought about by pin 54 on lever 55 dropping into therecess 56 in the edge of the cam 52.
When this occurs, spring 57 turns the. lever -55-clockwise (inFig. 1) thus rocking thethree-armed lever 58 on its supporting pin 18; the link 59 connects the lever 55 to one.
arm of the lever 58. The upwardly extending. arm of lever 58 carries a pin 60 which projects over the lever 38 carrying the rack bar 32, so that when the lever 58 is rocked as just described, the lever 33 is turned in the coins are fed. At the same time, and bythe same movement, the downwardlyextending arm of lever 58 acts through the links 61, pin 62 fastened to the bell crank lever 63 mounted on the pin 20, this lever 63, and pin 64 mounted on the temporary or supplemental backer @8, to slide the latter upwardly to its position in Fig. .3. The rack bar remains out of engagement with the pawl 33, and temporary or supplemental backer 48 remains in its upper or backing position, until the cam 52 is turned far enough (it turns in the direction of the arrow in Fig. 1) for the advancing wall of recess 56 to press the pin 54: out of the recess. WVhen this occurs, the lever 55 is turned in the reverse direction. backer 4:8 is moved down out of the path of the coins along the stacker bars 3 and 4, and the ratchet bar 32 is allowed to engage against the pawl 33. The recess 56 is so large that this action is delayed an adequate time for the spring 31 to return float 30 to the backer 48, and of course this action takes place before enough coins have been thrust toward the hacker 4:8 to cause jamming at this point. 7
